Not as part of Dawarich itself, but I think combination of our free tools will do it for you:
- Convert your KMLs to GPXes: https://dawarich.app/tools/gpx-to-kml/
- Merge your GPXes to a single file: https://dawarich.app/tools/gpx-merger/
- Import your chonky GPX into Dawarich itself :)
No data sampling is being done as of now, but it might be introduced some time later :)


It’s also an option, of course, and I will post changelog to our blog, but as you could’ve read in the post, you can say no to the changelog feature and no request to chibichange will ever be made. You’re safe :)
